Arsenal and France international defender William Gallas was disappointed with the French fans after they jeered off Les Bleus' after the disappointing 0-0 draw in their Euro 2008 opener against Romania.
"For me, it is incomprehensible," said the Gunners skipper.
"We are giving all we can to get a good result, we go to the middle of the pitch to applaud our supporters who were about to leave and we receive whistles.
"It is a shame. I am no longer used to people whistling at me, and that is the case for most of us who play abroad.
"It surprises me."
